Our country benefits when smart and skilled immigrants come here, but there has to be limits. And we must calculate the impact on our own citizens who must compete with them for jobs. Where does our primary responsibility lie? The decade ending in 2010 was the highest in our history in terms of legal immigration(13.9 million) but during the same period we suffered a net loss of jobs if 400,000.
Unfortunately the majority of even our legal immigrants have been of the low-skill variety. It is that heavy welfare/EITC/Medicaid population that is a drag on the economy. If we had a more skilled workforce—but truly we must recognize many IT jobs are only of the mid-skill, commodity variety—we wouldn’t see as much offshoring.
